Instructor Presence in Online Case Discussions: A Social Network Analysis

• In Event: Discussing Online Discussions

Abstract

Discussion is an essential component in case-based instruction (CBI), as it offers students the opportunity to consider diverse perspectives, clarify confusion, and construct understanding. However, without instructor presence, students may be unwilling to participate actively in case discussions to share views and exchange information. We used social network analysis (SNA) to explore the influence of instructor presence in case-based discussions. Specifically, we considered how the instructors’ role shifted across multiple online case discussions and affected student interactions and the development of an online community. Preliminary results show that interactions among students increased after the instructor moved away from the facilitation center to disseminate information. Suggestions are provided for instructors to support peripheral and isolated students.
